I received the chair as I was getting ready to leave for an appointment. I decided to open the box to see what would be involved to set it up. Although the chair came partially disassembled, it took less than 20 minutes to unpack and assemble it. The back and the legs were not attached. The legs needed to be screwed on but the back simply had to be inserted into the metal slots on the arms. I managed to put it together with plenty of time to make my appointment!
